g Indium has two naturally occurring isotopes: 113In with an atomic weight of 112.904 amu, and 115In with an atomic weight of 11

aleksandrvk [35]

Answer:

Fraction-of-occurrences of 115In isotope $= 0.957$

Explanation:

As we know weight of 113 In isotope is equal to the sum of product of fraction-of-occurrences of two constituents isotopes and their atomic weight

$^{115}In_w = f_{113}*A_{113} + f_{115}*A_{115}$ ------(1)

As we know sum of fraction-of-occurrences of two constituents isotopes is equal to one.

$f_{113} + f_{115} = 1\\f_{113} = 1- f_{115}$ ---------(2)

Substituting the given values in equation 1, we get

$^{115}In_w = f_{113}*A_{113} + f_{115}*A_{115}\\114.818 = (1 - f_{115}) * 112.904 + f_{115} * 114.904\\f_{115} = 0.957$

Substituting this value in equation 2 we get -

$f_{113} = 1- f_{115}\\f_{113} = 1- 0.957 \\f_{113} = 0.043$

Which characteristic of life is demonstrated when human skin heals after it has been cut?

Levart [38]

Answer: B. reproducing

Explanation:

Reproducing is the characteristic which contributes to the production and generation of new cells in the body from the pre-existing cells through cell division and cell differentiation. This process helps in replacement of old and damaged cells of the body.

According to the given situation, the human skin heals as the skin cells performs the process of reproduction in which the new cells are formed from the pre-existing cells to replace the dead and damaged cells of the region of cut.

Why should antibiotics be used as a last resort rather than a first line of defense against bacteria

stepan [7]

Doctors would let your body's immune system fight off a bacterial infection. If the infection gets worse, then the doctors would proscribe you with some antibiotics so it'll fight off the harmful bacteria.
